I thought it was worth trying sketching again considering the diabolical weather. This is done with white charcoal pencil on black cartridge paper (and so isn’t reversed in the scan). This I found actually much easier than sketching in pencil. It shows the craters Orontius, Saussure, Huggins, Nasireddin and Miller and is drawn from a photo taken at 21h15 on 28th April this year.

A beautiful halo showed all evening today. Jupiter is also visible just to the right of the Moon.

This morning gave a really excellent view of Jupiter in the Dobsonian. The sky was lightening constantly as I watched and the reduction in contrast against the sky I believe enhanced considerably the view and removed any diffraction spiking that might have intruded. Venus as a semi-crecent and Sirius were also prominent.
